“Ah! Here’s something -” Sirius muttered to himself as he rifled through the contents of Filch’s filing cabinet. The caretaker seriously needed to get rid of those creepy shackles ... and maybe think about moving that baloney and mustard sandwich, which was beginning to attract a lot of flies. He pulled out a nose-biting teacup and examined it to make sure it wasn’t broken, but after finding a chip on the rim of the cup he tossed it aside. He had broken in with the plan of locating the rocket that Filch had confiscated a week prior, but this scheme was turning out to be a lot harder than he had originally thought. Not discovering anything else in the filing cabinets aside from a fanged frisbee and some detention slips, Sirius went over to the desk and pulled out the top drawer. Inside, he found a golden snitch rolling about in it’s contents, figuring that was something James would like, he grabbed it.
Unfortunately, there was a noise looming closer from the hallway that sounded an awful lot like the caretaker himself. Quick as he could, Sirius swung himself over the desk and ran out of the office and down the hallway, not chancing to look back in case the caretaker was right behind him. However, he must have been spotted because there was a voice yelling after him. Down the stairs he went, past a corridor with a red tapestry, through an archway ... he ran as fast as he could, not daring to take a secret passageway as Filch knew them well-enough and could easily catch him at the wrong turn.
As Sirius looked back to see if he was still being followed, he ran into someone by accident. Horrified, he looked back and saw a girl that was a little familiar to him. He took this moment to catch his breath as he leaned against the wall with a laugh at the ridiculousness of the situation. “Sorry for taking your breath away like that, love, but have you seen an old git wandering around lately? A bit smelly, thinks all students are scum, and has a strange fantasy about hanging us by our ankles in the dungeons?”
